adding/setting a cookie vb.net

Question

I know how to add / set cookies in VB.Net , usually I check if it is null ( or Nothing in VB) if it is nothing I set a new cookie , if it is not then I set the value of the previous cookie. My question is there any thing wrong , or any down side to just adding a cookie every time like this:

HttpContext.Current.Response.Cookies.Add(New HttpCookie("Lat", dt(0)(1).ToString().Trim()))

I'm hoping that this will just override the previous Cookie("Lat") if it exists , and set a new one if it doesn't , if this works it will really make my code a lot shorter and make things easier. I don't see why this wouldn't work - but every tutorial and example online normally checks if it exists first.

Use Set method instead of Add. Reference MSDN

If you want to add (duplicate) cookie into the collection then use Add method and want to update an existing cookie then call the Cookies.Set method. (Reference MSDN)
